Q. 12. What are the decrees of God?
A. God’s decrees are the wise, free, and holy acts of the counsel of his will, whereby, from all eternity, he has, for his own glory, unchangeably foreordained: Whatsoever comes to pass in time, especially concerning angels and men
So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers, to equip his people for works of service, so that the body of Christ may be built up until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.
